/**
 * This module adds the autocomplete=off attribute to selected key user forms.
 * On a browser that respects this setting, it means that the browser will not
 * try to autocomplete the password on the user login forms, or the whole
 * user edit form.
 *
 * Many browsers, including current Chrome as of this writing and LastPass
 * do not respect this setting. But it can
 * 1. Offer some security on the login form
 * 2. Prevent naive users from getting the browser-fill on the first password
 *    form and not the second, making them angry and confused.
